Unable to connect to mycloudex2ultra from browser on home network

I have had this NAS device running for about 3 years now as a backup device for a Windows laptop. Recently it has stopped being accessible form my home network and I can’t even connect to it on a browser to check it out. It shows up as being connected on my Router and I can see the IP address but can’t access it.
Can anyone suggest anything to try?


Are you still using OS3? If yes then you may be better off placing this topic in the sub-forum for your device. You can try \\WDMYCLOUD and see what happens. You can turn off internet access and then try the same IP address to see what happens.

Are you able to update your device to OS5?

This sub-forum is for the single bay WDMYCLOUD 1st generation.

Note there are specific subforums for My Cloud EX2 Ultra discussion.

OS5 (v5.x) Firmware My Cloud EX Series

If one is having trouble accessing their OS3 My Cloud from the same local network there are a few troubleshooting steps to try. If using a Windows computer, enable SMB1.0. Microsoft disables this setting in new Windows installs and in update patches.

Also on Windows computers make sure the Windows Network Profile is set to Private and not Public. Also check that any third party security or firewall programs are not blocking local network SMB/Samba access.

Ensure all devices on the local network are using the same workgroup name and have IP addresses within the same IP address range as the My Cloud.

If one has recently changed their network router/gateway one may need to perform a 4 second reset of the My Cloud to change the My Cloud DHCP option back to default of obtaining an IP address from the local network DHCP Server. In certain cases a 40 second reset can fix certain My Cloud issues.

One can also try accessing the My Cloud Dashboard by its IP address.

Note: Since April 15, 2022 WD has ended support for OS3 My Cloud firmware and disabled their methods (mycloud.com and OS3 My Cloud mobile apps) of OS3 My Cloud remote access. For OS3 My Cloud devices one can continue to use local network access. My Cloud EX2 Ultra users should update their devices to OS5 if they haven’t done so already to regain myloud.com and OS5 My Cloud mobile app remote access to their device.

My Cloud OS3 End of Service

Q: Will my device stop working if I can’t upgrade to My Cloud OS 5? Will I lose access to my data?
A: After the services are shut down, you can only access the device on a local network. Access through the My Cloud OS 3 mobile app or web app won’t work. Email notifications won’t be delivered. Devices that had auto-update enabled received a final firmware update that disabled remote access and outbound traffic to cloud services. Now, support has ended and you have to use your local network to access your device.
